Tubes for fuel, electricity or coolant can also be passed through the wholes of the elements. With a corresponding design, the volume of the plates can be used to store gases and liquids.
Here, the passenger cell (roof, side walls and floor plate) can be entirely produced from the structure plates. The rigidity of the plates can be sufficiently dimensioned so that the grid frame necessary up to now can be done without. After the calculations have been implemented, a floor plate of 50 mm thickness is sufficient to guarantee the necessary rigidity.
